WARWICKSHIRE’S Mat Jackson grabbed two victories as the Silverline Chevrolet team dominated the day’s racing in the British Touring Car Championship at Silverstone yesterday.

Colin Turkington Increased his lead over Fabrizio Giovanardi at the top of the overall drivers’ standings to 11 points – but couldn’t find a way past the Silverlines.

Henley-in-Arden ace Jackson took the spoils in race one and race three, with team-mate Jason Plato triumphing in race two as their Lacettis proved to be the cars to beat at the Northamptonshire track.

Team RAC BMW driver Turkington bagged a pair of fourth places and claimed a third place from the final race of the day, while Vauxhall driver Giovanardi claimed two fifth places and a race two podium.

Jackson admitted he could hardly have hoped for a better day.

The 28-year-old said: “To get a win and a podium in the first two races was fantastic, but the final victory from seventh on the grid was awesome. That’s two meetings in a row that I’ve finished on the podium in every race, not something that many drivers can boast.”

Former Formula One driver Johnny Herbert endured a difficult introduction to touring car racing as he finished 13th and eighth in the opening two races before being taken out of race three by Plato, who was handed two points on his competition licence and an official reprimand.
